Abstract
Adhesion of Helicobacter pylori to both human gastric carcinoma cell lines (MKN45, MKN28 and KATO III) and prepared primary human gastric epithelial cells were analyzed with flow-cytometry. All strains adhered to human gastric carcinoma cells. Especially, these strains strongly adhered to MKN45 cells. Adhesion of H. pylori strains to prepared primary human gastric epithelial cells was also observed. However, the adherence rates of H. pylori to these cells were different among the cells used. These results suggested that the host factor might be important for adhesion of the bacteria to human gasgric cells. In addition, H20 monoclonal antibody directed to H. pylori HSP60 inhibited the adhesion of H. pylori to both cells. These results indicate that H. pylori HSP60 might be associated with the adhesion of the bacteria to human gastric epithelial cells.
